Re: Amp for 4pi speakers
In my experience, 200Hz is about the limit of the flanking sub (helper woofer) approach. But I've blended the woofer with the mid(woofer) to ~250Hz in some loudspeakers and it has worked well.
Some specialized cases, like the constant directivity cor...

Re: Amp for 4pi speakers
Hi Wayne
Thank you for your quick and helpful answer!
You're right about the notch at 120hz. I always like to smooth the measurements a bit because it gives a good feeling.

It looks like you've done a very good job already, and I have no doubt you'll tweak your system further to make it even better still.
Congratulations!

Re: Is a home theatre system really necessary?
You might expound upon what you mean by "actual home theater system."
My personal definition is any audio/video system that is setup to play movies. Many of them double as music playback systems for their owners.
So from this definition,...

Re: The shape of the room
The ideal room is outdoors, because there are no walls or ceiling to act as reflectors. Obviously, that's not an option so next best thing would be a very large, well-damped room having randomly contoured walls with no large flat surfaces. That's proba...

Re: The shape of the room
Square rooms aren't good because room modes are strong. You would definitely benefit from multisubs - in any small room actually - but even more so if the room is square.

Re: Will it work? Audio in conservatorie?
You can use seven π cornerhorns with distributed multisubs or four π mains with flanking subs and possibly one or two distributed multisubs. Either setup will work for you in that room, and I think they'll sound pretty good. I always prefer constant di...

Re: Horn mouth vs. front baffle or "speaker cone"

Re: Two Subwoofers
Outside and inside are very different.
Outside, you want all sources to combine coherently. This means you want sound sources grouped together, and their acoustic centers aligned.
When two subs are placed at each ends of a stage, bass suffers from...
